Definitions

  • This invention relates to improvements in a single facer.
  • FIGS. 1 and 2 Conventional single facers are shown in FIGS. 1 and 2 (i.e. like EP-A-0024817).
  • FIG. 1 shows an upper roll 1 having its external circumference formed into a corrugated shape and a lower roll 2 having the same external circumference as above in corrugated form.
  • a sheet S 1 of card-board fed into the meshing portion between said upper and lower rolls 1 and 2 is processed into a corrugated sheet S 2 .
  • the corrugated sheet S 2 is brought into contact with a pasting roll 7 so that a paste 8 can be applied to the top portion of the corrugated sheet S 2 and, together with another sheet S 3 supplied from other direction, it is pressed and heated by the engaging point between a pressure roll 3 and the lower roll 2 until it is finished as a single-faced corrugated board S.
  • FIG. 3 shows an enlarged view of the pressing and heating step of the sheets 2 and 3 by the engaging point between the lower roll 3 and the pressure roll 3.
  • FIG. 2 shows also another conventional example designed to prevent the generation of the aforesaid vibrations.
  • a pressure member 10 in place of the pressure roll 3 shown in FIG. 1, there is provided a pressure member 10 in a position facing the lower roll 2 as shown in FIG. 2, said pressure member having a diameter or a curved surface equal to, or a little larger than, the diameter of the lower roll 2 so that there occurs no change in distance between the pressure member 10 and the lower roll 2 from an engaging point A to another engaging one B, as shown in FIG. 4.
  • the pressure member 10 has a curved surface of a length larger than the distance I between the teeth of the lower roll 2 and the pressure member 10 is pressed against the lower roll 2 in order to keep the sheet S 3 and the corrugated sheet S 2 in close contact so that, in the process of the engaging point A to B shown in FIG. 4, a contact portion C between the sheet S 3 and the corrugated one S 2 is subjected to frictional force between the sheet S 3 and the pressure member 10. Under such circumstances, the sheet S 3 does not advance to the same extent as the amount of progress of the corrugated sheet S 2 with the result that there occurs a relative lag between both until the contact portion C becomes separated as a conventional drawback which has heretofore been common in practice.
  • the present invention aims at removing and improving all the aforegoing drawbacks of conventional facers. So the object of the invention is to provide a single facer, extremely simple in operation and compact in structure.
  • the advantage of the invention is a single facer which is designed to draw cardboard sheets by means of a conveyor so as to eliminate a difference in relative speed between the sheet and the corrugated sheet in a manner to prevent a strip-off phenomenon between both at their contact portion, thereby not only improving the quality of cardboard sheets but also enhancing their usable percentage.
  • FIGS. 1 and 2 are explanatory views in outline of conventional different facers respectively.
  • Numeral 1 is an upper roll for guiding a sheet S 1 , 2 a lower roll rotating in engagement with the upper roll 1, 7 a pasting roll for contact with the lower roll 2, 8 a paste adhering to the surface of the lower roll 2, 10 a pressure member provided in engagement with the lower roll 2 and having the same diameter as that of the lower roll 2 or a curved surface larger than that and adapted to pinch and hold a corrugated sheet S 2 between the lower roll 2 and the pressure member 10, a sheet or web sheet S 3 being conducted through a preheating roll or friction roll 17,11 a driving shaft, 12 a driven shaft, 13 a plurality of belts constituting a suction conveyor, 13' a suitable number of suction holes formed in the belts, 14 a suction box provided at the lower side of the belts 13, 15 a duct connected to a suction blower 16, 18 and 19 frames, 20 a chain wheel for the driving shaft 11, 22 a chain wheel for the lower roll 2, the chain wheels 20 and 22 being connected together by means of a chain 21
  • All the belts 13 are disposed near downstream of the engaging point between the lower roll 2 and the pressure member 10 and a plurality of belts 13 are provided in parallel so as to ensure a suitable distance between the ends of the adjacent belts 13.
  • the suction box 14 At the lower surface of these belts 13 is arranged the suction box 14, part of spacing therebetween being connected to the suction blower 16 through the duct 15.
  • the driving shaft 11 and the driven shaft 12 are rotatably attached to the frame 19 which is secured to the frame 18.
  • the power of the driving shaft 11 is transmitted by the chain wheel 20 secured to the end of the driving shaft 11 by means of a key, the chain wheel 22 secured to the end of shaft of the lower roll 2 and the chain 21, and the chain wheels 20 and 22 are selected such that the circumferential speed of the belts 13 can become equal to or a little larger than the circumferential speed of external diameter of the lower roll 2. Also, the transmission of power of the driving shaft 11 becomes possible by means of a speed-variable electric motor (not shown).
  • the sheet S 2 processed into corrugated form due to meshing of the upper roll 1 and the lower roll 2 may be brought into contact with the pasting roll 7 so that the paste 8 can be applied to the top end of said corrugated form and said sheet S 2 together with the sheet S 3 supplied from other direction can be fed to the engaging point between the lower roll 2 and the pressure member 10 or a pressure roll (not shown) until they become a single-faced corrugated board S. Subsequently, the single-faced corrugated board S can be drawn in its condition closely attached to the belts 13 due to suction pressure of the suction blower 16 for supply to the next step.
  • the single-faced corrugated board S can be brought into close contact with the belt 13 and drawn at the same speed as the circumferential speed of the lower roll 2 without slipping so that there occurs almost no difference in relative speed between the sheet S 3 and the corrugated seet S 2 which may otherwise arise from frictional force between the sheet S 3 and the pressure member 10 or the rotation or resistance of inertia of the preheating roll 17 and a paper-winding roll (not shown), thereby preventing the strip-off or separation of the sheets S 2 and S 3 at the aforesaid contact portion C.
  • FIG. 7 shows another preferred embodiment of the present invention wherein there is provided a mechanism for controlling the tension of sheets being fed from a paper roll portion.
  • the driving shaft 11 for driving the belt 13 is rotatably attached to the frame 19.
  • a hub 26 is secured to the end of the driving shaft 11 by means of a key, and a check plate 29 and a friction plate 31 are adapted to slide in the axial direction on the external circumference of the hub 26.
  • the external end of the hub 26 is formed into a threaded portion to which is applied a nut 27.
  • a dish spring 28 is incorporated between the nut 27 and the check plate 29.
  • the chain wheel 24 is also incorporated between the friction plates 25 and 31 and a bushing 30 and the.chain wheel 24 are adapted to slide in the circumferential direction.
  • the dish spring 28 can be resiliently transformed in shape by turning the nut 27 and its counter force acts as a contact power between the friction plate 31 and the chain wheel 24 and also between the friction plate 25 and the chain wheel 24 through the check plate 29.
  • an electromagnetic coupling may be used to achieve the same function as that of said preferred embodiment as a matter of course.
